Application October 25,

6 Claims.

This invention relates to coin controlled scoreboards to be employed for keeping scores of various games, such as ten pins, and has for the primary object, the provision of a machine of the above stated purpose in which plain paper may be used instead of the usual ruled forms,- resulting in a large saving in the cost of operation, such plain paper may be purchased at a much lower cost than the ruled forms.

Another object of this invention is to provide a scoring board which will collect payments for the game before delivering scoring paper for use.

With these and other objects in View, the invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following de- 20 scription and accompanying drawings, in which Figure 1 is a perspective view illustrating a coin controlled scoreboard constructed in accordance with my invention.

Figure 2 is a diagrammatical View illustrating the wiring diagram of the coin controlled mechanism.

Figure 5 is an enlarged fragmentary transmeral 5 indicates a casing which may be of any desired shape, preferably of a general outline representing a desk having an inclined top wall 5 and vertical supporting walls 1. The top wall 45 6 is provided with an opening 8 to expose a ruled transparent panel 9. Said panel bears the markings usually found on forms employed for keeping score in thegame of ten pins. The upper and lower edges of the panel 9 are spaced from the upper and lower edges of the opening 8 to define'paper feed slotsill so thatpaper of a transparent nature may be fed out of the casing and across the panel and back into the casing as suggested in Figure 3. The markings on -6. the panel will be visible through the paper due .verse sectional View showing in dotted lines the 1938, Serial No. 236,952

(01. asp-s) by a player or players for the purpose of keep- 10 ing a record of their scores.

Located in the compartment i3 is a skeleton frame M for supporting the electric lamps directly under the panel and the paper in rolled form, as clearly shown in Figures 3 to 5 of the 15 drawings. A shaft I5 is journaled in the frame It on which the roll of paper is mounted. Feed rollers l6 are journaled on the frame Ml directly below the paper feed slots H! and have secured thereon sprocket gears ll over which a sprocket chain I8 is trained. The paper as it unrolls passes over the lowermost feed roller then outwardly of the casing by one of the slots l0 and across the panel 9 and back into the casing by Way of the other slot l t and in engagement with the other feed roller,- whence it passes downwardly and through the slot in the partition l2.

A ratchet gear is is secured on one of the feed rollers and is engaged by a gravity actuated dog 20 pivoted on the frame l4 and is provided with a reduced extension 2!. The heavier side of the dog from the pivot is next to the ratchet gear so that said dog will maintain automatically a position in engagement with the ratchet gear to prevent rotation of the feed rollers until the dog has been disengaged fromthe ratchet gear.

A lever 22 is pivotally mounted on the frame M, as shown at 23, and is substantially in the form of' a bell crank and has pivoted to one end an arm 24 carrying a roller 25 engageable with vthe extension 2| of the dog 2%. A dog 26 is carried by said end of the lever 22 to engage with the sprocket chain it. The other end of the lever 22 has pivoted thereto an arm 27 slidable between guide rollers 28 journaled on a guide member 29 slidably supported by guides 30 mounted on the frame M. The free end of the arm 21 is arcuately curved, as shown at M, to engage with a pin 32 of an operating lever 33, when said arm 21 is allowed to assume its lowermost position, as shown in dotted lines in Figure 5. The operating lever 33 is secured on a shaft 34 journaled in the frame it andextends through a wall of the casing 5 a-ndhas secured thereon an operating handle 35. 55

The member 29 is supported in a raised position by a catch 36 which forms a core of a solenoid 31. The member 29 also has journaled thereon a roller 28' to engage with the arm 24 and to support the arm 24 in a raised position out of engagement with the extension 2| of the dog 20 when the member 29 is in its uppermost position supported by the catch 35.

A stop 39 is provided on the frame l4 for limiting the pivotal movement of the lever 22 in one direction under the influence of a spring 48. The lever 22 is free to assume the dotted line position, as shown in Figure 5, when the catch 36 releases the member 29 and allows the latter to gravitate to position the arm 21 in its lowermost dotted line position as shown in Figure 5 to lie in the path of movement of the pin 32 of the operating lever 33 so that when the operating handle 35 is rotated in the proper direction the lever 33 will impart an endwise movement to the arm 21 causing the lever 22 to assume the dotted line position, as shown in Figure 5, the arm 21 moving into the uppermost dotted line position as shown in Figure 5. As the lever 22 moves into the dotted line position the arm 24 forces the extension 2| of the dog downwardly disengaging the dog from the ratchet gear l9 freeing the feed rollers for operation. As the lever 22 moves into dotted line position, the dog 26 being in engagement with the sprocket chain pulls thereon and thereby drives the feed rollers to feed the paper across the panel 9. As the operating lever 33 continues its rotation past the uppermost dotted line position in Figure 5 it becomes disengaged from the arm 21 allowing said arm to assume a full line position. When the arm 2'! assumes the full line position in Figure 5, the spring 4|! returns the lever 22 to its full line position against the stop 39 and withdraws the roller of the arm 24 from the extension 2|. As the lever 33 moves beyond the uppermost dotted line position shown in Figure 5 to become disengaged from the arm 21 the member 29 is elevated so that the catch 36 may move thereunder for supporting the member 29 in a raised or elevated position, as shown in full lines in Figure 5.

An arm 49 is pivoted on the frame I4 and carries a pressure roller 4| which rides on the paper as the latter passes over the uppermost feed roller. A tension spring 42 connects the arm 49 to the frame I4 for urging the pressure roller 4| against said feed roller. An arm 43 is pivoted on the frame l4 and carries a pressure roller 44 urged into engagement with the lowermost feed roller by a spring 45, it being understood that the paper passes between the pressure roller 44 and the lowermost feed roller.

Whenever it is desired to adjust the paper on the feed roller or to place new paper in the device, the roller 4| may be positioned as shown in dotted lines in Figure 5 and held in this position by a prop provided on the frame engageable with a pin on the arm 49.

As before stated, the catch 35 forms a part of the core of the solenoid 31' and an expansion spring 46, shown in dotted lines in Figure 5 is arranged in the solenoid for the purpose of ur ing the catch 35 normally into engagement with a keeper 41. The catch 36 when in engagement with the keeper 4'! underlies the member 29 and supports the latter against downward movement so as to position the arm 21 in the full line position, as shown in Figure 5.

Arranged in the casing 5 is a coin chute 48 emptying into a coin drawer 4-9 and having its upper end in communication with a coin slot 50 located in the top wall 6 of the casing. A coin operated switch 5| extends into the coin chute 48 to be engaged by a coin as the latter gravitates through the coin chute to the coin receptacle. The switch is of any well known construction and controls an electric circuit which will be hereinafter fully described in detail. Positive and negative electric feed wires 53 and 52 extend into the casing 5 and are connected to an electric output in any well known manner. The feed wires 52 and 53 have connected thereto conductors 54 and 55 providing an electric circuit for the electric lamps used for the illumination of the panel 9. The positive electric feed wire 53 connects with the switch 5| and also connected to the switch 5| is a conductor 56 which is in turn connected to a solenoid 51. The solenoid 51 is employed for operating a rotary type circuit closer G9 which will be hereinafter described in detail. A conductor BI is connected to the solenoid 51 and to the negative electric feed wire 52.

The rotary switch or circuit breaker 69 consists of a rotatably mounted ratchet gear 62 carrying an arm 63 providing a movable contact adapted to move into and out of engagement with a series of contacts 54. Matching the contacts 64 are contacts 65 connected by conductors, as shown at 66. Operable from one contact 65 to another is a manually actuated switch 61. A dog 68 coacts with the ratchet gear 62 and is pivotally mounted on a lever 69 and the latter is pivotally supported at one end and has its other end connected to the core of the solenoid 51 by a link 1|]. The lever 69 is urged in one direction by a spring H and in a direction opposite to the movement thereof by the solenoid 5'! when energized. A spring 12 influences the dog 68 in engagement with the ratchet gear 62 of the switch 60. A pivotally mounted holding dog 14 engages with the ratchet gear 62 of the switch 60 by the action of a spring 15. The holding dog 14 is pivotally mounted and associated therewith is an electric magnet 13 which when energized will attract the holding dog 14 and disengage the same from the ratchet gear 62. A clock type spring 11 is provided for rotating the ratchet gear 62 in a direction opposite to its rotation by the dog 68 and solenoid B1. The core of the solenoid 31 has an extension 18 for operating a switch 18. The contact arm 63 is connected to the negative wire 52 by a conductor and the electromagnet '16 is also connected to the negative wire 52 by a conductor 8|. The electromagnet 16 is connected to the switch 19 by a conductor 83. The switch 19 is connected to the electromagnet 28 by a conductor 84 and the latter is connected to the positive feed wire 53 by a conductor 85. The solenoid 31 is connected to the switch 61 by a conductor 85'.

Through the use of the switch 61 and the contacts 65 the electrical parts of the device may be manually adjusted to require the payment of one or more coins for the operation of the machine. For instance, if the switch 6'! is positioned as shown in Figure 2 it will require the payment into the machine of three coins. As the first coin is deposited in the coin slot and gravitates to operate the switch 5| the solenoid 57 is energized advancing the contact 83 one step or into engagement with the first of the series of contacts 54. The ratchet gear of the switch 60 is held from reverse movement by the holding dog 14'. The second coin when dropped into the coin chute operates the switch 5| for the second time energizing the solenoid 51 which through the dog 68 advances the contact 63 a second step and into engagement with the second contact of the'group of contacts 64. "On the deposit of the third coin the switch is actuated again energizing-the solenoidbl, advancing the contact 63 into engagement with the third contact of the group of contacts 64. The switch -61 being in engagement with the third contact of the group of contacts 65 brings about an energizationgof the solenoid. 31. The ene'rgizatio-n of the solenoid operates the catch 36,- allowing' the membertfl togravitate'and the arm 21 to assume its lowermostjdotted'line position, as shown in Figure. 5.
